 These signals are being shot up into the atmosphere and bounced back down to Earth. Like Over-The-Horizon radar / The Russian Woodpecker / HAARP-like technology, etc. There are multiple frequencies used. Specific frequencies. When combined, they create an interference signal in the ELF range that can transduce into physical / mechanical vibration and sound. This was done over Eugene Oregon in the 70's as a test. With the Woodpecker during the same time frame and then HAARP and HAARP-like technology. It's everywhere now. It can be used to basically X-Ray all of Earth (Earth Tomography)..including beneath the ground, it can interfere and hijack the Schumann Resonance with the power levels used and can be used to create all sorts of ELF trickery when interacting with human bodies. Which is the main use. These days, it is much more advanced and operates as a two-way / network no different than wireless internet. These signals can be found in recordings that were made at 85,000 feet in the air and even up to 115,000 feet in the air. The same signals that can be found in a home or in a cave. There is a lot more to it...but that's an extremely rough skeletal.
